Students are introduced to basic theoretical and implementation principles of the following topics: construction, use and mutual transformations of finite automata, regular expressions and regular grammars, translation finite automata, construction and use of pushdown automata, hierarchy of formal languages, Relationships between formal languages and automata. Knowledge acquired through the module is applicable in designs of algorithms for searching in text, data compression, simple parsing and translation, and design of digital circuits.

1. Motivation to study formal languages. Basic notions (language, alphabet, grammar, automaton), Chomsky hierarchy. 2. Nondeterministic and deterministic finite automata (NFA, DFA), NFA with epsilon transitions. 3. Operations on automata (transformation to NFA without epsilon transitions, to DFA, minimization), intersection, union. 4. Programming implementations of DFA and NFA, circuit implementations. 5. Adding translation, Mealey, Moore, conversions. 6. Operations on regular grammars, conversions to FA. 7. Regular expressions, regular expression conversions, finite automata and regular grammars, Kleene theorem. 8. Principles of use of regular expressions in UNIX (grep, egrep, perl, PHP, ...). 9. Finite automaton as a lexical analyzer, lex/flex generators. 10. Properties of regular languages (pumping lemma, Nerode theorem). 11. Context-free languages, pushdown automaton. 12. Parsing of context-free languages (nondeterministic versus deterministic). 13. Context-sensitive and recursively enumerable languages, Turing machine. Last update: Jirát Jiří (09.01.2014)

Students will be able to: Understand finite automata, regular expressions, grammars, and translation finite automata, with an emphasis on their practical use. Understand the class of context-free languages, basic use of pushdown automata, as well as the classification of languages. Last update: Jirát Jiří (31.01.2014)
